Application filed March 1, 1922. Serial No. 540,295.

Fire-Extinguisher Holders; and we do hereby declare that the followingis a full,

clear, and exact description thereof.

Our invention relates particularly to the means for supporting andcontaining the receptacle for the tire extinguisher liquid.

The invention has for its object to provide a fire extinguisher of thistype in which the receptacle or extinguisher proper is completelyenclosed and thereby guarded against tampering while at the same time,according to the presentinvention, permitting of inspection. Ourinvention also aims to prevent, in an extinguisher of this type, theaccidental turning of the handle, by vibration for instance. It also hasfor its object to provide for the receptacle or fire extinguisher properbeing readily set in place and held steadily against displacement by adetachable connection at the bottom and a clasping device' near the top;a further object being to prevent vibration of the glass forming thefront of the containing means in which theV receptacle or .tireextinguisher proper is contained, the glass exposing the fireextinguisher proper and preventing unauthorized access thereto withoutthe breaking ofthe glass.

More specifically stated the invention consists of an upright oblongrectangular box the front of which has a transparent face, preferably asheet of glass slid into guides from one end, preferably the top. Thebottom ends of these guides terminates at the bottom of the box whilethe opposite ends or tops are closed by a slide slipped into place andlocked after the glass has been inserted. The purpose of this lock is topermit the slide to be removed and the glass to be withdrawn to take outthe lire extinguisher proper to be tested. The re extinguisher proper isslid in place by a double spring clip secured to the back of the box, aspring clip the ngers of which clasp the receptacle near its upperend, aslotted bracket fastened in the bottom of the box to receive the nozzlein the lower end of the receptacle, vwhile the glass is held againstvibration by the pressure of springs within the box and pressing itagainst its guides.

For full comprehension, however, of our invention reference must be hadto the accompanying drawings in which similar reference charactersindicate the same parts and wherein:

Figures 5 and 6 are also horizontal sections taken on line 5-5 and 6 6respectively, Figure l; and

Figure 7 is a vertical sectional view taken on line 7 7 Figure 3 andillustrating the,

means for holding the glass.

Figure 8 is an enlarged sectional view of the top of the supporting boxland illustrating more clearly the upper end of Figure 2.

The) box of our fire extinguisher is of the type usually employed forfire extinguishers of the pump type and is of oblong form and verticallydisposed with open front covered by a sheet of glass The sides Z), backc, top d and bottom c are intact while the front edges of the sides areflanged as at j and the bottom is turned up over the lower ends of theseflanges as at g and soldered in place. The front edge of the top has aturned down front flange j to serve as a back rest for the top edge ofthe glass and its side edges are y turned upwardly and inwardly as at mto present guides for the removable locking slide 7c which also has afront flange z' to lock the glass in place. All these parts are and maybe of usual construction.

Heretofore considerable trouble has been experienced from the fact thatit has not been possible to remove the lire extinguisher proper from itsbox without breaking the glass. We overcome this defect by form ing thetop of the box with a central opening n inwhich the lower end of a key 0carried by a slide 7c protrudes, thus locking the slide in lace after ithas been slid to position holding the upper end of the glass. This keytherefore consists of a screw-bolt the slot of which is of special formto receive a special key to prevent tampering. This special form mayconsist, as shown, of notches g in the opposite side of the top of thebolt and in diametrical line thus presenting a relatively raised centralportion r flush with the top of the bolt. A key s is suitable for such aloclr. rlhis loclr is threaded through a nut u soldered to or otherwiserigidly secured upon the top of the slide in juxtaposition with theopenings therethrough. lllith this construction., upon unlocking theslide it may be withdrawn and the glass removed)` thus permitting thefire extinguisher to be taken out and inspected and if necessaryrecharged.

Another defect in connection with lire extinguishers of this type hasbeen that vibration of the building train or vessel in which they arelocated caused the handle to be turned and the extinguisher to leali.Vibration also causes vertical displacement of the fire extinguisherproper and sometimes it is displaced laterally. All this shiftingdainages the extinguisher and tends to destroy its effectiveness. lVehave succeeded in eliminating these disadvantages by attaching withinthe box to the back thereof at the top a duplex spring clip presenting aforwardly extending U-shaped clip 2 adapted to receive and clasp thestem 3 of the handle of the extinguisher and an upwardly and forwardlyextending clip prese ting two downwardly acting spring lingers ladaptedto press upon the top of the handle and hold the extinguisher yieldinglyand firmly with its nozzle in engagement with a slotted bracket 5 theslot 6 in which receives the nozzle 7 of the extinguisher. This bracketis preferably of angular torni one leg being rive-ted to the back of thebox near the bottom, the other leg of which eX- tends parallel to theAlatter and slightly above it while the end of this leg has a turned downfoot El soldered to the, bottom of the box. "he pressure of thepresserfingers l maintains the fire extinguisher firmly against verticaldisplacement. The clip 2 and the slotted bracket are suppleinented inthe function of preventing lateral displacement and the tireextinguisher is stabilized by a spring clip 9 riveted to the back of theboX in position to have its arms clasp the extinguisher near the top ofits 1 ,ascisse body portion. Coaction of these three sustainingeleinents el'ectively prevents any displacement either vertically orlaterally of the extinguisher proper within the bei; and at the sai letime permits it to be removed after the glass has been taken out.

rllhe glass is held firmly against its guides by a pair of spring-wireholders adapted to bear against the edge portions of the inside surfaceof the glass and cause it to be held firmly in its guides.

llVhat we claim is as follows:

l. A lire extinguisher helder consisting of an oblong bei: with baclnsides bottom and top and an open front, the sides and top having inwardflanges and the top flange being set rearwardly from the side flanges; aslide `upon the top and presenting a flange overhang-ing the flange atthe top; and means for locking the slide in place.

2. A fire extinguisher holder consisting of an oblong box with back,sides, bottom and top and an open front, the sides and top having inwardflanges and the top flange being rearwardly 'from the side flanges; aslide upon the top and presenting a flange overhanging the flange at thetop; and means for locking the slide in place, such means consisting ofa loclt carried by the slide and adapted to engage an opening in the topof the boa.

3. A.. `fire extinguisher holder consisting of an oblong befr with back,sides7 bottom and top and an open front, the sides and top having inwardflanges and the. top flange being set rearwardly from the side flanges;a slide upon the top and presenting a flange everhanging the flange atthe top; and means for locking the slide in place, suoli meansconsisting of a lock carried by the slide and adapted to engage anopening in the top of the box, such lock' consisting of .a nut carriedrigidly by `the slide and a bolt threaded through the nut and havingnotches in the sides of its upper end for the purpose described.

ln testimony whereof we have signed our naines to this specification inthe presence of two witnesses.
